5 Second Timer Circuit Diagram. This is a protection circuit to protect any electrical or electronic equipment and appliance from sudden high or unstable. Hi in the second diagram using a 1000uf and a 2m2 resistor at the base of the npn should produce a delay of over 2 minutes if it s giving 0 5 seconds then there could be something seriously wrong with your circuit.
This is done by pressing the inc button. These on off intervals can be adjusted by varying the 555 timer output and number of counter outputs. Hi in the second diagram using a 1000uf and a 2m2 resistor at the base of the npn should produce a delay of over 2 minutes if it s giving 0 5 seconds then there could be something seriously wrong with your circuit.
This is done by pressing the inc button.
The on time of the load is then entered by the user. Programmable industrial timer circuit diagram circuit description.
